<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

  <dependencies>   
    <dependency>

        <artifactId>tools</artifactId>
        <version>1.5.0</version>
        <scope>system</scope>
        <systemPath>${java.home}/lib/tools.jar</systemPath>
    </dependency>
  </dependencies>

PS: here, <profiles> and <dependencies> must be sepreated, or it cant solve the problem.
